    Product Features

    3D Customisable, Precise

    First-rate 3D view with high-fidelity CAD drawings, customizable shortcuts, and real-time colour-coded progress maps — with quick switching between 2D and 3D modes.

    Easy to Use

    A simple wizard calibration process gets you working immediately, with remote access, troubleshooting, and data sync handled through CHCNAV's iSite cloud platform, plus OTA updates.



    Excellent Compatibility

    Supports a wide range of attachments and widely compatible radio protocols, including Satel external radio modules, with built-in editable coordinate system presets and support for multiple design file formats.

    Reliable Hardware

    High-reliability industrial design built around the high-performance MC300 receiver, an IP69K-rated IS300 IMU sensor, and an IP68 GNSS antenna with a metal bottom shell.

    Detailed Specifications

    High-Fidelity 3D Guidance

    Full 3D view, top view, side view, and big-font information view, with high-fidelity CAD drawings for genuinely clear design reference.

    Layer-Based Elevation & Horizontal Guidance

    Full control over data visibility, letting operators focus on exactly the guidance they need for the task at hand

    Wide Attachment Compatibility

    Supports standard bucket, tilt bucket, tiltrotator, and trapezoidal bucket, with separated calibration so components can be freely combined.

    Cloud-Connected Workflow

    A local region-based cloud platform enables file distribution and remote access from anywhere, cutting time lost to on-site file transfers.

    Quick Field Surface Design

    Design surfaces directly in the field, streamlining the workflow without needing to return to the office.

    Industrial-Grade Reliability

    IP69K and IP68-rated components built to withstand genuine construction site conditions, not just office/lab environments.
